caption_attribution_description: Latina: Naevus acralis (20x) English: Acral naevus Polski: Znamię dystalne W niektórych miejscach wydłużone sople naskórkowe zlewają się ze sobą, co może być niepokojącym objawem. Również widoczne na mikrofotografii wnikanie melanocytów w bardziej powierzchowne warstwy naskórka (ang. Melanocytic acral naevus with intraepidermal ascent cells; MANIAC) może skłaniać do rozpoznania czerniaka, choć jest obserwowane w tym typie znamienia.
context_page_description: An acral nevus is a cutaneous condition characterized by a skin lesion that is usually macular or only slightly elevated, and may display uniform brown or dark brown color, but often with linear striations.
  They are nevi of palms and soles, which may occur in all ethnic groups but more common in dark skin people. Acral Nevus is a benign skin tumor that can occur at any age, but is generally noticed between 10–30 years of age. Both children and adults may be observed with this skin tumor. Prevalence of aural nevi increased directly with degree of skin pigmentation. In a study palmar or plantar nevi were detected in 42.0%of black vs 23.0% of whites. Palmar or plantar nevi of 6 mm diameter or larger were detected in 3.4% of blacks vs 0.6% of whites.
  These are brown to dark brown in color and have linear streaks of darker pigmentation. Size is 7 mm or less, oval or spindle shaped, and are well demarcated. They become stable after initial growth phase and the number of lesions also decrease, new lesion in middle age or elderly should raise suspicion of acral lentiginous melanoma.
